The invention provides a parking control method and device, and an electric vehicle, and relates to the technical field of vehicle control. The method comprises the steps of acquiring a current demandtorque sent by a vehicle controller and a driving mode of the vehicle; if the driving mode is a single-pedal mode and the current demand torque is a negative torque, acquiring a first motor rotatingspeed at an interval of a first preset duration in response to the current demand torque; and making the vehicle park according to the first motor rotating speed. According to the scheme, a speed closed-loop control method is adopted so that the rotating speed of the motor of the vehicle is zero, parking of the vehicle is achieved, a problem that the vehicle slides backwards is avoided, and driving safety and driving convenience of a driver are improved.

    本发明提供一种驻车控制方法、装置及电动汽车,涉及整车控制技术领域,所述方法包括:获取整车控制器发送的当前需求扭矩和汽车的驾驶模式;若所述驾驶模式为单踏板模式且所述当前需求扭矩为负扭矩,则在响应所述当前需求扭矩时,间隔第一预设时长获取第一电机转速;根据所述第一电机转速,控制所述汽车驻车。本发明的方案,通过采用速度闭环控制方法,使汽车的电机转速为零,实现汽车的驻车,避免出现车辆后溜的问题,提高了驾驶安全性和驾驶员的驾车便利性。
